Models of tag shedding for double tagging as a function of time at liberty and approximate solutions for the single tagging model in CASAL
Abstract: The model of tag shedding implicit in CASAL is that of Kirkwood and Walker (KW) (1984 ... ) which models the annual tag shedding (i.e. loss) rate as a constant for individual tags. The CASAL ... software applies this model correctly for fish released with a single tag but does not have the facility at ... present to correctly apply the KW model for fish released with two tags. The solution of Dunn et al. (2005 ...
